Abstract: Disclosed wing-to-body join methods include commanding a wing to a first command position and then iteratively repeating a first-phase movement and/or commanding a wing to a second command position and then iteratively repeating a second-phase movement. The first-phase movement includes determining a real position of the wing, calculating a first-phase difference between the real position and the first command position, and commanding the wing to reduce the magnitude of the first-phase difference. The second-phase movement includes determining a real position of the wing, determining a real position of the body, calculating a second-phase difference based on the second command position and the real positions of the wing and body, and commanding the wing to reduce the magnitude of the second-phase difference. Some embodiments include performing a port-side move for a port wing of the aircraft and performing a starboard-side move for a starboard wing of the aircraft.

Abstract: The disclosed subject matter includes techniques for performing a channel availability check. A method includes initiating, via a processor of a master device, a first connection on a first wireless channel with a subordinate device and transmitting, via the processor, a beacon to the subordinate device. The method includes monitoring, via the processor, the first wireless channel for a first predetermined amount of time for a connection request from the subordinate device in response to the beacon. The method includes performing the channel availability check to detect energy profiles on a second wireless channel for a second predetermined amount of time after the first predetermined amount of time. The processor may cycle between transmitting the beacon and monitoring the first wireless channel and performing the channel availability check on the second wireless channel until a threshold time is exceeded, the connection request is detected, or an energy profile is detected.

Abstract: An apparatus for propulsion includes a main body, a fluid flow channel for fluid mass to circulate within a self-sealed apparatus, an air flow channel for air to circulate within a self-sealed apparatus and/or to the open environment, a fluid mass, a rotator having compartments to move the fluid mass centrifugally, a cover providing sealed containment for the apparatus and providing the means to remove the rotator from the main body, and a rotator shaft providing rotation to the rotator by motor. A preferred embodiment includes an apparatus with two or more fluid flow channels for fluid mass to circulate within a self-sealed apparatus. Another preferred embodiment includes an apparatus with two or more air flow channels for air to circulate within a self-sealed apparatus and/or to the open environment. And another preferred embodiment includes the main body that can be manufactured in one or more parts.

Abstract: A blend of polymers comprising from 5 to 95 weight % of a polymer having a high molecular weight made using a single site type catalyst and from 95 to 5 weight % of a polymer having a lower molecular weight made using a catalyst containing a phenoxide, preferably a salicylaldimine ligand, has an excellent toughness and would be suitable for use in applications such as polyolefin pipes.

Abstract: Olefin polymers having a conventional comonomer incorporation, a reverse (or partial reverse) comonomer incorporation or a substantially flat comonomer incorporation with a broad, bimodal or multimodal molecular weight distribution are produced under a process using a single site catalyst with the combination of a phosphinimine and/or ketimide compound, and an aluminum compound in a cyclical controlled increase of the ratio of hydrogen to ethylene and controlled or uncontrolled decrease of the ratio of hydrogen to ethylene if plotted as a function of time.

Abstract: Properties of a polymer produced using a dual catalyst on the same support, such as polydispersity and comonomer incorporation, may be controlled by controlling reaction parameters such as temperature, monomer pressure, hydrogen partial pressure and the presence of non-polymerizable hydrocarbon. This provides an easy method to control the bimodality of a polymer as well as comonomer incorporation.

Abstract: Bimodal polyolefins having a reverse or partial reversed comonomer incorporation may be prepared in the presence of a dual catalyst on the same support wherein each catalyst has a different response to temperature, ethylene partial pressures, partial pressure of non-polymerizable hydrocarbons present in the reaction mixture and hydrogen partial pressure.

Abstract: Polymeric supports, which have been treated with a halosulfonic acid, increase the activity of single-site catalysts used with aluminoxane co-catalysts, resulting in improved ethylene polymerization. The present invention seeks to provide polymeric catalyst supports which have been treated with halosulfonic acid for improved activity.
